Misato Uehara (上原美里Uehara Misato), known by fans as the "real Misato Uehara" is Nana Osaki's maternal half-sister by their mother, Misuzu Uehara. Though she bares a striking similarity to Nana, she is unaware of her true relationship with Nana and ironically became one of her newer devoted fans. She also has an older brother named Takahiro and lives in Osaka, where her parents own an okonomiyaki shop.
